DRY METHOD DEVELOPMENT FOR LASER DIFFRACTION PARTICLE SIZE MEASUREMENTS. Developing an appropriate method for measuring particle size distribution of powders dispersed in air using laser diffraction requires a structured approach.
The basic goals for developing a dry method include: place a representative sample into the analyzer, disperse the sample using a pressure that breaks up agglomerates but not .cross-validate the particle size range of the sample. Figure 2 illustrates the progression of an agglomerated sample toward stable dispersion. Images show agglomera-tion when only the dispersion cell stirrer and pump are active; however, when ultrasound is applied particle size reduces to a stable level. The leveling of particle size sug-
